Wow, the migration of the offline storage from file to database did take very long. I thought one or two hours are enough. No, the scripts ran for 10 hours. Therefore the Jabber/XMPP services were offline for about 10 hours, from ~10:30 pm CEST yesterday to 8:50 am CEST today. We are very sorry about that. Good news: No more big downtimes are planned in the near future.
